Generalized Differential Quadrature Method for Vibration Analysis of Cantilever Trapezoidal FG Thick Plate

This paper presents a numerical solution for vibration analysis of a cantilever trapezoidal thick plate. The material of the plate is considered to be graded through the thickness from a metal surface to a ceramic one according to a power law function. Kinetic and strain energies are derived based on the Reissner-Mindlin theory for thick plates and using Hamilton's principle, the governing equa...

hydrodynamic analysis of circular and non-circular journal bearings using generalized differential quadrature method

this paper presents the application of the generalized differential quadrature (gdq) method for the hydrodynamic analysis of circular and noncircular, two lobe and three lobe, journal bearings. gdq is a simple, efficient, high-order numerical technique and it uses the information on all grid points to approach the derivatives of the unknown function. the effectiveness of the solution technique ...

Analysis of Free Vibration Sector Plate Based on Elastic Medium by using New Version of Differential Quadrature Method

The new version of differential quadrature (DQ) method is extended to analyze the free vibration of thin sector orthotropic plates on the Pasternak elastic foundation with various sector angles and elastic parameters. Detailed formulations are given. Comparisons are made with existing analytical and/or numerical data. Numerical results indicate that convergence can be achieved with increasing i...

Magnetic Stability of Functionally Graded Soft Ferromagnetic Porous Rectangular Plate

This study presents critical buckling of functionally graded soft ferromagnetic porous (FGFP) rectangular plates, under magnetic field with simply supported boundary condition. Equilibrium and stability equations of a porous rectangular plate in transverse magnetic field are derived. The geometrical nonlinearities are considered in the Love-Kirchhoff hypothesis sense. The formulations are compa...
